The U.S. Securities and Exchange Commission (SEC) announced a postponement of its decision on Grayscale’s proposed spot Cardano (ADA) exchange-traded fund until October 26, 2025. This extension aligns with recent SEC behavior of lengthening review periods for several spot crypto ETF filings.

Grayscale’s filing—intended to bring ADA exposure to regulated markets—remains active in the regulatory process. The SEC’s extension follows filings such as the NYSE Arca 19b-4 submission and administrative listings in regulatory portals of Delaware, which indicate continued procedural progress.

How does Cardano’s tech progress affect ETF prospects?

Cardano’s introduction of the Halo2-Plutus verifier brings zero-knowledge proof integration to its smart contract layer. These upgrades enhance privacy, on-chain scalability, and developer tooling—factors that institutional investors cite when evaluating long-term network resilience.
